To all 'wh/om 'iz may concern.'

Be it known-thatA l'` PAUL L. lnocnann'r, a citizen ot the United States. residing at Hamilton, hio, have invented a new and arful Improvement in Marigles, ot which the following is a specitieatimi.

My invention relates to mangles ot the class wherein the linen is carried hetween the face of a rotative r .'lindri ^al drier and an endless apron whereon pressure is exerted at` intervals hy melun,` ol-p1'essure rolls, and the objects ot my improvements are to provide fulcrumed levers wherein the roll hearings are slidahly mounted and hand actuated lever n'lechanism for siin\ilt':u1eously moving the levers with the rolls toward or from the drier; to provide yielding connec" tions between the disk and the actuating lcver mechanism thert-.tore so that the pressure rolls may he raised automatically and simultaneously hy obstructions passing therenntfler, and to provide such simple and durahle construction ot the dill'erent memhers to facilitate their assenlhlage and operation for securing the most etlicient aetion. These objects are attained in the tollowing deserihed manner as illustrated in the accompanying drawings, in whichz' l`igure l is :tu end elevation with parts broken away ot' a mangle enlhodying my improvements; Fig. 2 a longitudinal verticat' section with parts hroken away; Fig. El, a side elevation with parts in section; Fig. 4l-

a sectional. view showing the sliding connec tion of the lever `with the disk, and l"1gs.-5

and t3 a plan with parts in section and an end elevation respectively showing the yielding connection of the\lever mechanisn'i with the disk.

ln thedrawings, l represents the usual end supporting trames ol' a mangle, 2 a hollow cylindrical drier journalcd thereon, :l portions ot an endless apron partially encircling the drie and arranged to travel in the direction ot the arrows. Angular levers ileach formed with a slotted housing (l in its outer end are fulcruxned at intervals on the end trames and equidistant from the axis ot the drier hy means ot holts 7. Disks s rotatively adjustable on the respective journals t) o'tf the drier are cach provided with a series ot radial slots ll equidistant from `its axis and slidahly engaging with the pins 5 secured in the inner ends 'ot the corresponding levers Ll. Pressure rolls 12 are journaled at their respective ends in hearings 13 which areslidahly mounted in the slotted housings 6 ofA the angular levers #1. Coil springs 14 emplaeed within Said l'iousings may he regulated hy means of ad justing screws l5 tor moving and maintaining said hearings in contact with the bottom of the slots in the housings.

A shaft lti journaled an the end frames in hearings 17 islfn'ovided .vith a hand lever 18 and with crank arms lt). Rods 2.1 curved and connected at one end to the respective crank arms are adjistahly secured at their other end to the slotted housings 22. Bean ings 23 slidably mounted in the respective said housings are pivotally secured to and near the periphery oi. the corresponding disk 8. Coiled springs 24 emplaced within the respective housings 22 may he adjusted hy means ot'serews Q5 in one end thereof tor umintaining the hearings 223 under a yielding pressure in contact with the opposite end ot the slots therein as shownin Fig.

ln operation. the springs t'or the roll hear` ings may he adjusted as desired for light pressure ot the rolls on the apron, 1and the spring in the connecting rod housing may be adjusted to maintain the hearing inunovahle therein. For heavy work however, the latter spring mayr he adjusted to exert a light yielding pressure on the connecting rod hearing and the lformer springs may he adjusted to maintain the roll hearings suhstantially immovahle whereby the passing ot an obstruction under one of the pressure rolls will cause the. correspolnling angular levers to rotatively aetuate the disks to compress the springs in the connect-v ing rod housings and litt all the pressure rolls simultaneously.

The angular arms are constructed in such manner that they may he used interchangeahly and for either end of either of the rolls. The hand lever serves to turn the shaft with the crank arms on a dead center in relation to the connecting rods wherehy the rolls may he moved and maintained under great pressure with relatively little exertion ot the operator.

Having fully described my improvements,

what I claim as my invention and desire to secure by Letters Patent of the United States is 1. A mangle comprisingend frames, a drier journaled thereon, anA endless apron partially encircling the drier, disks mounted concentric with the ends' of the drier, interchangeable angular levers fulcrumed at intervals on the frames and movably engaging with the disks, pressure rolls carried by said levers and coperating with the drier, and lever. mechanism yieldingly lconnected with the disks whereby the levers may be moved and maintained with the rolls under a yielding pressure on the apron in contact with the drier.

2. A mangle comprising end frames, a drier journaled thereon, pressure rolls cooperating With the drier, rotatively adjustable disks, lever connections between the rolls and disks, a shaft provided with a hand lever and with crank arms, and curved pitman adj ustably connecting th disks with said arms for automatically locking the disks with the crank arms on the center."

3. In a mangle the combination of a drier j ournaled in fixed bearings, interchangeable angular levers fulcrumed at fixed points in relation thereto, pressure rolls movably supported by said levers for coperating With the drier, an apron interposed between the rolls and. the drier, adjusting springs for maintaining the respective rolls with the apron in contact With the drier under different yielding pressures, and adjustable lever mechanism for simultaneously `moving andmaintaining the levers with the rolls and apron under proportionately increased pressures.
